Dreamrunner & Drekavac

Dreamrunner
An agile enemy that flips about the area, attacking with the blades it holds in each hand. It looks vaguely human, wearing a tattered tasset around its waist and a pale grinning mask. It has the ability to travel around through portals it creates, and can deflect many of Dante's sword and bullet attacks, even countering his aerial combos. Dreamrunner has a stronger variation, Drekavac.

Drekavac
A stronger version of the Dreamrunner which appears to combat Dante on several occasions before finally revealing it's name before entering the Furnace of Souls. It wears a red mask instead of Dreamrunner's blue, and is far more agile and capable of countering.
